Influence of photoperiod on the behavioral response to olfactory stimulation in the snail Helix pomatia L.
An ethanol vapor concentration of 1.6 mmol/l was used to test the diurnal variations of the olfactory response in two groups of snails, which were adapted to different light-dark cycles. The results revealed that the olfactory sensitivity to stimulation with ethanol was significantly increased during the day-time, which corresponds to the scotophase of the light-dark cycle, to which the animals...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Potassium channels in the central nervous system of the snail, Helix pomatia: localization and functional characterization.
The distribution and functional presence of three voltage-dependent potassium channels, Kv2.1, Kv3.4, Kv4.3, respectively, were studied in the central nervous system of the snail Helix pomatia by immunohistochemical and electrophysiological methods. Cell clusters displaying immunoreactivity for the different channels were observed in all parts of the CNS, although their localization and number ...
متن کاملMathematical model of pacemaker activity in bursting neurons of snail, Helix pomatia.
On the basis of experimental data we have developed a mathematical model of pacemaker activity in bursting neurons of snail Helix pomatia which includes a minimal model of membrane potential oscillation, spike-generating mechanism, voltage- and time-dependent inward calcium current, intracellular calcium ions, [Ca2+]in, their fast buffering and accumulation, stationary voltage-dependent [Ca2+]i...
متن کاملTransmembrane outward hydrogen current in intracellularly perfused neurones of the snail Helix pomatia.
The ionic nature and pharmacological properties of the outward current activated by membrane depolarization were studied on isolated neurones of the snail Helix pomatia, placed in Na+- and Ca2+-free extracellular solutions and intracellularly perfused with K+-free solution ("nonspecific outward current"). It was shown that the amplitude and reversal potential of this current (estimated from ins...
